A patient has a history of chronic obstructive pulmonary disease. The patient's oxygen flow rate should be set to no more than:
A) 5 to 10 L/min.
B) 4 to 5 L/min.
C) 2 to 3 L/min.
D) 1 to 2 L/min.

Question

Quizplus · Accepted Answer

Patients with obstructive lung diseases should be given only 2 to 3 L/min because higher concentrations of oxygen reduce the respiratory rate. This is because their incentive to breathe comes from lower oxygen levels rather than higher carbon dioxide levels in the blood (they usually have a continuous high level of carbon dioxide).
